Benefits of Installing a Metal Roof Over Shingles

Putting a metal roof over shingles comes with several perks. Firstly, metal roofing is lightweight. This simplifies the installation process over old shingles. It saves money on labor since you don’t have to take off the old shingles.

What’s more, metal roofs are a cost-effective solution. In the long term, they outlast asphalt shingles. They can remain in good condition for over 50 years, whereas asphalt needs replacing every 20 years.

Metal roofs are extremely durable. They ward off fire, rot, and bugs. With this durability, they could protect your home for a very long time. They’re also energy-efficient. By reflecting heat, they keep the inside cool. This can lower your cooling expenses.

Another plus of putting on a metal roof is not having to deal with the messy removal process of old shingles. It makes the whole installation process less of a hassle. This does away with some of the disturbances and saves time and effort.

Considering all these advantages, installing a metal roof over shingles is a smart move. It’s both cost-effective and efficient for those wanting a lasting, energy-saving roof.

Drawbacks of Installing a Metal Roof Over Shingles

There are many good things about a metal roof over shingles. But, you should know about the possible downsides too. It’s wise to look at both sides before deciding.

Building Code Restrictions

First things first, check the local building rules. Some places might not allow you to put a metal roof over shingles. Following these rules is key to avoid trouble later on.

Potential Hail Damage

Hail damage is a risk with metal roofs over shingles. Larger hailstones can leave dents. To be safe, pick a metal roof known for its hail durability. Also, make sure it’s installed correctly. Getting the right insurance for hail damage is smart too.

Professional Installation Required

Professional hands are a must for a metal roof over shingles. This job needs special skills and know-how. Hiring the best ensures a proper job. Plus, it might be needed to keep the roof’s warranty valid.

Steps to Installing a Metal Roof Over Shingles

Putting a metal roof over shingles is a detailed process. It starts by checking the plywood under the shingles. This is to make sure it’s in good shape, free of rot. If the plywood looks good, move on to the next step.

That next step is adding a synthetic underlayment. This acts as a barrier. It keeps shingle granules from harming the metal. Plus, it makes the roof more waterproof, making everything stronger.

After this, you should think about adding insulation. E-foil insulation is a good choice. It helps the place stay cool in summer and warm in winter. This is added above the underlayment, boosting comfort inside the building.

Finally, it’s time for the metal panels. These give the roof its strength and look. They also help keep the air flowing and the building ventilated. Putting panels up right is crucial. They need to be fixed securely and aligned perfectly. This ensures they work well and last long.
